Answer 2

Given:

A body is revolving in a circle with decreasing speed.  

To find:

If V(VECTOR) be the velocity and A(VECTOR) be the acceleration at any instant, then

Solution:

If speed is decreasing the tangential acceleration will be in the direction opposite to that of the velocity.

The angle between the velocity vector and the net acceleration will be more than 90°.

α = 90° + θ

The angle between acceleration and velocity vector is more than 90° is the correct option.
